【摘要】：近年來,我國大力發(fā)展高速鐵路,客運(yùn)專線的建設(shè),在這些客專鐵路中,均采用了智能視頻監(jiān)控系統(tǒng)這種信息技術(shù)手段用以保障鐵路運(yùn)輸安全生產(chǎn)。 然而,我們也看到,視頻監(jiān)控系統(tǒng)在鐵路的應(yīng)用主要還集中在客運(yùn)專線鐵路,并且系統(tǒng)的功能,性能和應(yīng)用方式,應(yīng)用范圍等環(huán)節(jié)在滿足鐵路日益高效的行車保障需求方面的局限性越來越明顯。同時(shí),不僅高等級(jí)的客運(yùn)專線鐵路對(duì)視頻監(jiān)控系統(tǒng)有大量需求,視頻監(jiān)控系統(tǒng)在既有鐵路線的全面監(jiān)控也提出了強(qiáng)烈的需求。 近年來,隨著網(wǎng)絡(luò)帶寬的不斷增長(zhǎng),計(jì)算機(jī)技術(shù)的發(fā)展,圖像處理技術(shù)的提高,視頻監(jiān)控技術(shù)也有長(zhǎng)足的發(fā)展,視頻監(jiān)控應(yīng)用越來越廣泛地滲透到安防,教育,娛樂,醫(yī)療等各種領(lǐng)域。在短短的二十幾年發(fā)展歷程中,視頻監(jiān)控系統(tǒng)已經(jīng)經(jīng)歷了從第一代模擬系統(tǒng)(VCR),到第二代部分?jǐn)?shù)字化系統(tǒng)(DVR),再到第三代完全數(shù)字化網(wǎng)絡(luò)化的系統(tǒng)三個(gè)階段的發(fā)展演變。與之相對(duì)應(yīng)的,視頻監(jiān)控技術(shù)發(fā)展至今已經(jīng)歷了模擬監(jiān)控技術(shù),數(shù)字監(jiān)控技術(shù)和網(wǎng)絡(luò)監(jiān)控技術(shù)三個(gè)不同的階段。 鐵路智能視頻監(jiān)控系統(tǒng)直接服務(wù)于鐵路客貨運(yùn)輸生產(chǎn),鐵道部,路局,客專公司的各級(jí)用戶根據(jù)需要可選擇實(shí)時(shí)調(diào)用或回放各采集點(diǎn)視頻圖像,是運(yùn)輸安全的重要監(jiān)控手段。隨著客專線的快速建設(shè),智能視頻監(jiān)控系統(tǒng)的維護(hù)工作就變得日益重要,根據(jù)鐵道部的維護(hù)管理要求,各局按照管內(nèi)的實(shí)際情況分別制定了管內(nèi)智能視頻監(jiān)控系統(tǒng)的維護(hù)管理模式,劃定了維護(hù)管理分工界面,制定了應(yīng)急處置的各種預(yù)案。 雖然視頻監(jiān)控技術(shù)誕生已久,但是無論從視頻內(nèi)容處理角度,傳輸平臺(tái)角度還是從應(yīng)用全面性角度看,都遠(yuǎn)未達(dá)到成熟,還具有很大的發(fā)展空間。視頻監(jiān)控技術(shù)的發(fā)展依賴于視頻處理技術(shù)(包括視頻編解碼技術(shù),模式識(shí)別技術(shù),視頻檢索技術(shù)等),基礎(chǔ)網(wǎng)絡(luò)技術(shù)和相關(guān)信息集成技術(shù)的發(fā)展,緊密跟蹤這些基礎(chǔ)技術(shù)及其應(yīng)用的發(fā)展,是掌握視頻監(jiān)控技術(shù)發(fā)展趨勢(shì)的根本之道。 本文詳細(xì)闡述了智能視頻監(jiān)控在鐵路行業(yè)的應(yīng)用及其發(fā)展?fàn)顩r,描述鐵路智能視頻監(jiān)控系統(tǒng)的功能,性能,系統(tǒng)結(jié)構(gòu),結(jié)合當(dāng)前視頻監(jiān)控相關(guān)的關(guān)鍵技術(shù)的進(jìn)展,闡明未來鐵路視頻監(jiān)控系統(tǒng)技術(shù)和應(yīng)用的發(fā)展方向。
[Abstract]:In recent years, China has vigorously developed the construction of high-speed railway and passenger dedicated line. In these passenger dedicated railways, intelligent video surveillance system is used to ensure the safe production of railway transportation. However, we also see that the application of video surveillance system in the railway is mainly focused on the passenger dedicated railway, and the function, performance and application mode of the system. The limitation of application scope is more and more obvious in meeting the demand of railway traffic security. At the same time, there is not only a large demand for video surveillance system in high grade passenger dedicated railway, but also a strong demand for the overall monitoring of existing railway lines. In recent years, with the continuous growth of network bandwidth, the development of computer technology, the improvement of image processing technology, video surveillance technology also has a considerable development, video surveillance applications more and more widely infiltrated into security, education, entertainment, Medical and other fields. In the course of more than 20 years' development, the video surveillance system has experienced three stages, from the first generation analog system (VCR), to the second generation partial digital system (DVR), to the third generation complete digital network system. Correspondingly, the development of video surveillance technology has gone through three different stages: analog monitoring technology, digital monitoring technology and network monitoring technology. The intelligent video surveillance system of railway directly serves the railway passenger and cargo transportation production, the railway department, the railway bureau, the customer specialized company each level user may choose according to the need the real-time call or the playback each collection spot video image, is the transportation safety important monitoring means. With the rapid construction of passenger dedicated lines, the maintenance of intelligent video surveillance system has become increasingly important, according to the requirements of the maintenance and management of the Ministry of Railways, According to the actual situation in the tube, each bureau separately formulates the maintenance and management mode of the intelligent video surveillance system in the pipe, delimits the maintenance management interface, and formulates various contingency plans for emergency disposal. Although video surveillance technology has been born for a long time, whether from the point of view of video content processing, transmission platform or from the perspective of application comprehensiveness, it is far from mature and has a lot of room for development. The development of video surveillance technology depends on the development of video processing technology (including video coding and decoding technology, pattern recognition technology, video retrieval technology, etc.), basic network technology and related information integration technology. Closely tracking the development of these basic technologies and their applications is the fundamental way to grasp the development trend of video surveillance technology. This paper describes the application and development of intelligent video surveillance in railway industry in detail, describes the function, performance, system structure of railway intelligent video surveillance system, and combines the progress of key technologies related to video surveillance at present. The development direction of railway video surveillance system technology and application in the future is expounded.
